Newform orbit 175.4.a.i

Trace form

The 5 newforms in this orbit are conjugate over $\mathbb{Q}$ ; the sum of their $q$ -expansions is

$5q - 4q^{2} - 10q^{3} + 18q^{4} + 6q^{6} - 35q^{7} - 42q^{8} + 23q^{9} + 42q^{11} - 136q^{12} - 34q^{13} + 28q^{14} + 74q^{16} - 238q^{17} + 2q^{18} - 36q^{19} + 70q^{21} - 358q^{22} - 152q^{23} - 36q^{24} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate a number field of degree 5. It is generated by the eigenvalue $\alpha$ of $T = T_{2} + 3T_{3}$ , whose minimal polynomial is

$x^{5} + 34x^{4} - 180x^{3} - 9718x^{2} + 2211x + 629392$

Atkin–Lehner signs

$p$	$w_p$
5	— ( $5^2 \mid 175$ )
7	$+1$

For $p \parallel N$ every form in the orbit has $a_p = -p^{k/2-1} w_p$ .

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.139 s (one thread) and proven: the dimensions are certified, and the characteristic polynomial of $T$ over $\mathbb{Z}$ is reconstructed by CRT past a rigorous coefficient bound.

The engine's checks

dim M^+ at levels [1, 5, 7, 25, 35, 175]: [1, 3, 3, 9, 14, 62] (certified at ell = 2147482921)
T = [(2, 1), (3, 3)]; h of degree 29 = 1 x 29 (phi(ord eps) x dim S_k^new); 6 primes, 0 rejected
